<b>Purpose:</b> This study aimed to evaluate the clinical efficacy of contact diode trans-scleral cyclophotocoagulation (TSCPC) for treatment of refractory glaucomas. <b>Method:</b> Fifty two eyes of 52 patients, (post-penetrating keratoplasty glaucoma: 16 eyes; adherent leucoma with secondary glaucoma: 8 eyes; aphakic glaucoma: 6 eyes; neovascular glaucoma: 6 eyes; narrow angle glaucoma: 6 eyes; and other secondary glaucomas: 10 eyes) were followed up from 3.5 -18 months (average 12 months) after TSCPC. The treatment parameters using the contact G probe were - energy: 3-4J; area: 40 spots spread over 360&#x00B0;; site: 1.2-1.5 mm posterior to limbus. Retreatments (22 eyes; 42&#x0025;) were given whenever intraocular pressure (IOP) exceeded 22 mmHg despite maximum tolerable topical therapy. <b>Results:</b> IOP decreased from a baseline of 44.7 (&#x00B1; 7.3) mmHg to 15 (&#x00B1; 3.7) mmHg at first week and was 15.2 &#x00B1; (8.2) mmHg at the last follow up. Successful control of IOP (&#x0026;lt;22mmHg) occurred in 30 (58&#x0025;) eyes after a single treatment and in 48 (92&#x0025;) eyes following retreatment. Complications included reduction in visual acuity from light perception (LP) only to no light perception (NLP) in two eyes and phthisis bulbi in one eye. <b>Conclusion:</b> Contact trans-scleral diode laser cyclophotocoagulation is effective in lowering IOP in eyes with intractable glaucoma with few side effects in Indian subjects.
